BACKGROUND: The lymphocyte-monocyte ratio (LMR) in the peripheral blood is suggested to be a potential biomarker for predicting the clinical outcomes of several diseases. We aimed to evaluate the relative efficiency of LMR for predicting 3-month mortality in patients with acute-on-chronic liver failure (AoCLF). PATIENTS AND METHODS: In this study, 74 chronic hepatitis B patients, 90 AoCLF patients, and 70 healthy controls were followed up for 4 months. The primary endpoint was 3-month in-hospital mortality...

Hepatitis B virus (HBV) reactivation during chemotherapy is a major concern and is widely reported, particularly in association with hematological malignancies and lymphomas. While lung cancer ranks first in incidence and mortality worldwide, HBV reactivation has been largely overlooked in this disease. As regards small-cell lung cancer (SCLC), HBV reactivation has rarely been reported. We herein report the case of a hepatitis B surface antigen-seropositive SCLC patient in whom HBV was reactivated during the course of chemotherapy, despite preemptive use of lamivudine...

Patients ≥65 years with cancer remain underrepresented in clinical trials, particularly in phase I clinical trials. We analyzed the clinical course of patients ≥65 years treated on phase I clinical trials with particular emphasis on toxicities. We identified 347 consecutive patients ≥65 years with advanced cancer in our phase I clinic from 01/2004-12/2009 and analyzed disease characteristics, toxicities, survival and response. Overall, 251 patients received a targeted agent, of whom 241 (96%) received an investigational, non-FDA-approved drug...

Autophagy is an effective strategy for cell development by recycling cytoplasmic constituents. Genetic deletion of autophagy mediator Atg7 in hematopoietic stem cells (HSCs) can lead to failure of megakaryopoiesis and enhanced autophagy has been implicated in various hematological disorders such as immune thrombocytopenia and myelodysplastic syndrome. Here, we examined the hypothesis that optimal autophagy is essential for megakaryopoiesis and thrombopoiesis by altering autophagy using pharmacological approaches...

Deferesirox (DFX), an oral chelating agent, is used to treat chronic iron overload in several hematological diseases such as β-thalassemia, sickle cell disease, and myelodysplastic anemia. DFX is generally well tolerated with the exception of gastrointestinal disturbances and rash, although cases of renal toxicity, as well as acute and chronic liver failure, have been reported in adults and children. Here we describe a 3-year-old girl with β-thalassemia undergoing treatment with DFX who presented with acute liver failure and Fanconi's syndrome...

There have been no studies on the distribution of causes of macrocytic anemia with respect to mean corpuscular volume (MCV) cutoff values. We retrospectively investigated the causes of macrocytic anemia (MCV ≥100 fL) among 628 patients who visited the outpatient hematology clinic in Tohoku University Hospital. To ensure data validity, we also analyzed data from 307 patients in eight other hospitals in the Tohoku district. The leading causes of macrocytic anemia (number of patients, %) were myelodysplastic syndromes (121, 19...

Acute and chronic liver failure are associated with numerous alterations in different features of the coagulation system. Consequently, there is widespread confusion regarding the potential for both bleeding and thrombosis in patients with liver disease. The risk of bleeding is related to the hemodynamic changes in portal pressures and venous congestion whereas the thrombotic risk stems from changes in the coagulation system. Antithrombotic prophylaxis and treatment of patients with hemorrhage and thrombosis requires careful assessment, interpretation of laboratory workup, and attention to coexistent morbidities...

BACKGROUND: Genetic defects in telomere maintenance and repair cause bone marrow failure, liver cirrhosis, and pulmonary fibrosis, and they increase susceptibility to cancer. Historically, androgens have been useful as treatment for marrow failure syndromes. In tissue culture and animal models, sex hormones regulate expression of the telomerase gene. METHODS: In a phase 1-2 prospective study involving patients with telomere diseases, we administered the synthetic sex hormone danazol orally at a dose of 800 mg per day for a total of 24 months...

Hepatitis B virus reactivation (HBVr) is an important complication of immunosuppressive drug therapy (ISDT). It can occur with active or resolved hepatitis B virus (HBV) infection with a clinical spectrum that ranges from mild elevations in liver tests to fulminant hepatic failure. The risk of it occurring is determined by the interplay between HBV serological status, level of viremia, and the immunosuppressive potency of the drug(s) used. Reactivation is most common during treatment of hematologic malignancies but also occurs with chemotherapy for breast cancer and numerous other solid organ malignancies, organ transplant, and immune suppression for nonmalignant conditions...

Heart failure affects ≈23 million people worldwide and continues to have a high mortality despite advancements in modern pharmacotherapy and device therapy. HF is a complex clinical syndrome that can result in the impairment of endocrine, hematologic, musculoskeletal, renal, respiratory, peripheral vascular, hepatic, and gastrointestinal systems. Although gastrointestinal involvement and hepatic involvement are common in HF and are associated with increased morbidity and mortality, their bidirectional association with HF progression remains poorly fathomed...

The maternal-fetal interface is an immunologically unique site that allows the tolerance to the allogenic fetus and maintains host defense against possible pathogens. Balanced immune responses are required for the maintenance of successful pregnancy. It has been demonstrated that innate immune disturbances may be responsible for some adverse pregnancy outcomes such as preeclampsia (PE); hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome; intrauterine growth restriction (IUGR); and recurrent spontaneous abortion (RSA)...

We report a case of the extremely rare condition Epstein-Barr virus (EBV)-positive T-cell lymphoproliferative disease (LPD) which occurred after umbilical cord blood transplantation. A 25-year-old Japanese man underwent cord blood transplantation from a male human leukocyte antigen 4/6-matched donor due to acute myeloid leukemia with trisomy 8. Bone marrow examination on day 30 showed chimerism with at least 90% donor cells and complete hematological response. Chronic symptoms of graft-versus-host disease appeared only on the skin and were successfully treated with cyclosporine alone...
